concrete backer board - tiling bathroom

[gERM]

i'm thinking about tiling my shower walls; does anyone know if concrete backer board needs to be installed overtop of drywall, or can it be applied directly to wall studs? the stuff seems kinda flimsy, but seems like it'll be sturdy once applied to the studs (which are 6" apart). thanx...

Johnny,

What thickness board are you using? I normally use 1/2" or 5/8" and attach directly to the studs. If you already have drywall on the walls, there should be no harm in apply the board over it (assuming it is in good condition), you will just lose the additional thickness. I always use construction adhesive in addition to the screws to attach the board. I hope you meant every 16" on stud spacing or else your builder must have been getting paid by the piece!

By the way, how did you make out with your water pressure problems?

Good luck, Jim
